The year-end peak in Singapore runs from 11.11 through 12.12 and on into the Christmas rush, and for a small seller the thing that usually breaks first is not stock — it is the last thirty seconds of each order, where a shipping label has to come out of a printer and onto a parcel. Sorting that out in October costs a morning. Sorting it out at 1am on 11 November costs you your late shipment rate. Here is what to get ready.
Every parcel in Singapore ships on a 100×150mm label
Shopee, Lazada and TikTok Shop all issue their airway bills at 100×150mm (4×6"), and so do the local couriers you hand over to — SingPost, Ninja Van and the rest. There is no second format to hedge against, which makes the decision simple: your printer either takes a 110mm-wide roll or it cannot print a parcel label at all.
In our range that is the NIIMBOT B4, which supports 20–110mm label widths (108mm effective print width) and prints the 100×150mm courier size directly. The B31 tops out at 75mm and the K3 at 82mm — both excellent for product and shelf labels, neither able to print an airway bill. If you are weighing those two up, the B31 vs B4 comparison goes through it in detail.
Count your rolls now, not on the night
A peak-week order count is rarely a peak-week guess: take your best normal day, multiply by five, and buy label stock for that. The B4 label roll (50–110mm) carries the 100×150mm courier size, and the wider B4 Labels collection has the rest of the sizes that fit the machine. If you print at volume, the multi-roll packs work out cheaper per label than buying singles twice a week.
Worth knowing: label fitment runs one way. Anything up to 75mm made for the B31 also fits the B4, but the wide stock over 75mm fits only the B4. So a B4 owner can buy from either list; a B31 owner cannot.
Print the batch from a spreadsheet, not one at a time
Peak volume is where phone-by-phone printing stops working. Every NIIMBOT printer connects to the NIIMBOT app, and the app imports a spreadsheet and prints the rows as a batch — this is an app feature, so the whole range does it, not just the big models. Export your orders, map the columns, print the run. Our guide to printing labels from Excel walks through it step by step, and it is worth doing a dry run on ten rows before the sale, not during it.
The labels that are not courier labels
Peak season doubles the small stuff too. Fragile and handle-with-care markings, thank-you stickers for the repeat customers you are trying to earn, SKU labels so the picking does not slow down, price tags for anything you are also selling offline. A 2-inch machine like the B1 Pro or the B2 Pro handles all of that on 20–50mm stock while the B4 stays loaded with courier labels — which is faster than swapping rolls on one printer all evening. Plain white labels cover most of it; if anything is going into a chiller or a freezer, use the freezer label stock instead.
If your bottleneck is the shelf rather than the door, the warehouse SKU management page covers the setup side.
A ten-minute check before the sale
- Load a fresh roll and print one test label — see how to load and change a roll if the feed direction ever catches you out.
- Charge the printer fully, or keep it on mains if it is a desktop unit.
- Re-pair it in the app and print from the actual device you will use on the night.
- Keep one spare roll open and within reach of the packing table.
Nothing here needs ink, toner or a cartridge — every NIIMBOT printer is thermal, so the only consumable is the label itself. Browse the refills if you are topping up. Every printer ships from our Singapore warehouse with a 1-year local warranty, so order before the courier network itself gets busy — that queue gets longer in November too.
